First, the H drive is a reference to a source code path on our build machines - you'll notice it references a source code file (.cpp) which, of course, you also don't have (I hope!).
The first error indicates you're missing a wav file in the prompt folder - that's always bad and will cause the wheels to come off. I see this often with sites that try and remove prompts they don't want to hear without realizing this will break the system - could be an accidental deletion or sometimes with the add/removal of a language pack.
If you're not sure, you can always copy on the entire prompt folder from your install media onto the prompt folder in the Unity install path again - can't hurt.
